Test the air flow potentiometer with multimeter for voltage when engine idiling pin 1,2- 0.7V +- 0.1V The problem is that it probably worn the resistive material in the potentiometer and need to replace it because it gives the signal to the computer (ECU) and sends a signal to the stabilizer minimum valve (IACV).
Hey guys I was experiencing same problem I applied everything you suggested and it works perfectly fine but the idling sounds was higher But otherwise it's great
hellow, after buying this old benz did the ower clean the FUEL tank, tank filter , replace FUEL filter and on the FUEL line nipple filter etc on the engine side
Hey man, i wanna replace the fuel injectors on my 190e and im kinda new to working on my car. How did you remove the air filter housing? I removed the 3 bolts holding it in place. Kinda scared to remove the move the breather tube (most to the left of the 3 removable parts when looking at the air filter housing) should i just pull it out with a lot of force?
Great video. Did it jerk when putting into D? I have that same jerk, do you think it's caused by your idle air control valve problems or is it unrelated?
Brother: 1 owned W124-260E 1988 since 1993, the car is not on daily uses for the past 5 years. Problem: 1. It is easy to start but engine will knock & stop at the first hard press 2. If the engine continue ok- but after about 30 running idle, the engine stop & can not restart . After about an hour the engine can restart. Please advice
TorqREV almost anything changed that I can change on this engine, ovp , plug, electrical distribution( front orange ), washed throttle body, and ivc.... Only things that havent change is fuel distributor... damn that one expensive...

+190mex We have tried the potentiometer test prior to the methods in the video and it showed no deviations from the specifications.

Umm..late to catch on, but could you explain what was wrong how was it it determined and fixed?!? Please please please
Do I need to remove throttle body or just spray cleaner when engine is running
hellow, after buying this old benz
did the ower
clean the FUEL tank, tank filter , replace FUEL filter and on the
FUEL line nipple filter
etc on the engine side
+Hisham chohan The Mercedes has underwent a fuel system cleaning before and the filters replaced with new ones. Car runs fine now though
M102 owner here, had same problem, solve it by replacing potentiometer and disconecting ICV, runs on 1000rpm and it didn't stall for like 2 yrs now
What is icv, please explain.

Hi bro, bole guide utk w124 230e, lepas panas enjin... oil temp turun 3 ke 2 dan 1.

If you cant take of the air filter, I don't hold out much hope of you relacing the injectors.
@@stevesutton9444 replaced the injectors yesterday, miracles do happen haha
You guys are the BEST! Thanks for posting this video! VERY helpful!
Can’t spraying all that crap into the air filter housing cause problems to the engine?? Thought we didn’t want anything in there but oil.
Great video. Did it jerk when putting into D? I have that same jerk, do you think it's caused by your idle air control valve problems or is it unrelated?
It did. There was a vacuum leak. Do a smoke test.
@@TorqREV Doing it tonight

Sounds like you're running rich and having a hot start problem. Check your cold start valve first.
That really works! Thanks for this video. It was my lucky day because i seen that and finally fixed my car :D

cleaning the throttle also helps
I have a e34 bmw and just picked up A w124 260e for $650. It runs weird but it's pretty quick
Runs weird? Like what signals is it giving out?
TorqREV it has a weird idle and stutters under throttle
@@slowschoolofdriving218 Did you fix the weird idle and stuttering?
Sven Laansoo nope scrapped the car
@@slowschoolofdriving218 That's not what I wanted to hear :(
OVP Relay or just the fuse on the OVP relay ?
Usually I would replace the whole relay
I also have problem about the idle my mercedes w124 300e the rpm working too high with stay on 900rpm
Check your OVP relay.
The same problem. My car.
Please solusion.
What spray u use bro
Contact cleaner
@@TorqREV is it available at any spare part stockist or special order
Yup pretty much most hardware stores have it
@@TorqREV thanks for your information bro
عندي نفس المشكله محرك 300
what do you use on the throttle body?
+Chan BoEr We used contact cleaner on the throttle body.
TorqREV my e260 now facing a not stable rpm, just washed the ivc, but the result was not so good...
TorqREV btw, nice clean engine :D Hard to find such clean m103 engine in Malaysia anymore
+Chan BoEr You can try checking the OVP.
TorqREV almost anything changed that I can change on this engine, ovp , plug, electrical distribution( front orange ), washed throttle body, and ivc.... Only things that havent change is fuel distributor... damn that one expensive...
bro my 124 start the time rpm too high always stay at rpm 1500-2000
Check the throttle microswitch.
@@TorqREV ok tq bro
